@spec main() :: :ok

Allows to run command mix run -e 'NOAA.Observations.CLI.main()'.

The above command is equivalent to:
mix run -e 'NOAA.Observations.CLI.main([""ny"", ""16"", ""-t"", ""plain""])'

Examples

$env:MIX_ENV="test";      mix run -e 'NOAA.Observations.CLI.main()'
$env:MIX_ENV="dev";       mix run -e 'NOAA.Observations.CLI.main()'
$env:MIX_ENV="prod";      mix run -e 'NOAA.Observations.CLI.main()'
$env:AWAIT_TIMEOUT="111"; mix run -e 'NOAA.Observations.CLI.main()'

@spec main(OptionParser.argv()) :: :ok

Parses the command line and prints a table of weather observations from the NOAA Weather Service.

argv can be "-h" or "--help", which prints info on the command's usage and syntax. Otherwise it is a US state/territory code (case-insensitive) and optionally the number of observations to format (the first n ones).

To format the last n observations, specify switch --last.
To ring the bell, specify switch --bell.
To choose a table style, specify switch --table-style.
